As @uial pointed out, this is a picture of a Thangka painting from Tibet/Nepal which is made in a meditative state while reciting the mantra of Tara (Green, Red, White) thousands of times. Hence the energy from the painting, as also the sacred geometry aspect. 
Tara is a Goddess who embodies Compassion. Anyone who calls upon her for help gets help. She is also known as the “Mother of all Buddhas” because she holds the potential in Herself for all manifestations of Enlightenment. She appears in various forms: Green Tara (the protector - from ignorance, duality and from worldly troubles of all kinds), White Tara (long life and healing), Red Tara (manifestation and transmutation of desires), Blue Tara (transmutation of anger and fierce protection from attacks of all kinds, etc.)
And this picture is proof that her presence is felt when you sincerely call upon her. I held the picture, recited her mantra 21 times seeking her help, and posted it and could immediately feel her presence.
